SEC extends review period for Cboe FLEX options rule change to July 21
The U.S. securities regulator is giving itself more time to review a Cboe Exchange proposal affecting cash-settlement-eligible FLEX equity options tied to exchange-traded funds. The extension moves the decision deadline from June 6, 2026 to July 21, 2026, leaving more time to assess the filing and issues raised by the proposal.
Highlights
- Cboe Exchange filed a proposed rule change (SR-CBOE-2026-035) on April 9, 2026, to amend Rule 4.21 regarding cash-settled FLEX ETF options.
- The SEC extended its review period for the Cboe FLEX options rule change from the original June 6, 2026, deadline to July 21, 2026.
- The extension grants regulators more time to evaluate potential market impacts of the proposed changes affecting listed options on exchange-traded funds.
Extended timetable for ETF-linked options proposal
As reported by the Securities and Exchange Commission, Cboe Exchange filed the proposed rule change on April 9, 2026 under Section 19(b)(1) of the Securities Exchange Act of 1934 and Rule 19b-4. The filing seeks to amend Rule 4.21 on Series of FLEX Options in relation to cash-settlement-eligible FLEX equity options overlying exchange-traded funds.The proposal was published for comment in the Federal Register on April 22, 2026. Under the statutory review framework, the Commission normally has 45 days from publication to approve or disapprove a proposed rule change, or to institute proceedings to determine whether it should be disapproved, unless it designates a longer review period.
Regulatory impact on market process
The original 45-day review period for the filing would end on June 6, 2026. The SEC now designates July 21, 2026 as the date by which it must either approve or disapprove the proposal, or open proceedings to consider whether to disapprove it.The Commission says the longer period is appropriate because it needs sufficient time to consider the proposed rule change and the issues it raises. The filing is identified as SR-CBOE-2026-035 and remains part of the ongoing regulatory review process for exchange rule changes affecting listed options markets.
